Negative pressure pneumatic conveying system (dilute phase)

A pneumatic conveying system suitable for transporting powdered or granular materials from multiple starting points to a target point. Also known as vacuum conveying system.

Negative pressure conveying system can be defined as a method of conveying powdered or granular materials along a limited channel by suction. Named after the negative pressure of gas in the pipeline

characteristic

▲ No need for a rotary valve.

▲ It can be transported from several starting points to one target point.

The material enters the pipeline under normal pressure, making it easier to add the material.

During the transportation process, there is no need to cool the transported gas.

Even if the pipeline connection and sealing are not good, it will not cause powder leakage.

The material receiving hopper is always in a negative pressure state, and the negative pressure resistance performance needs to be considered.

The conveying pressure is only -0.4 to -0.5 kPa, so the conveying distance and amount are limited.

▲ It is almost impossible to achieve dense phase transportation.

Compared to positive pressure conveying, energy consumption is higher under the same conditions.
